Oklahoma Case Study: Cannabis Market Sizing and Underreporting of Cannabis Usage (Cannabit Graphic)
- By August 3, nearly 330,000 Oklahoma residents had registered as medical cannabis patients.
- Registered patients now account for about 11% of adults (age 18+) in the state, nearly matching its total estimated cannabis consumer population.
- What is being seen in Oklahoma illustrates complications from trying to measure cannabis use though self-reported surveys.
- Various factors may lead to underreporting during surveys, raising a question of possible self-censoring which may artificially suppress reported usage rates.
- As seen in markets having turned legal, margins of underreporting decrease with time following legalization, in tandem with actual increases in usage.
